Organic

There are many different species of thrips, but a biological control in the form of a predatory mite can be used on houseplants and in greenhouses to attack the western flower thrips. Organic pesticide sprays are available, which are based on plant oils or pyrethrum.

Chemical

Ornamental plants can be sprayed with insecticides containing methiocarb.
